			first thing I noticed: don't make 2L in a 2L keg. It fits almost exactly 2L, so all the CO2 gas sits in the neck; this means the interface between gas and liquid is tiny. Next time I should make 1.9L or something like that.

 After that, I’ll vent, pour in the first uncarbonated 1.5L batch (also refrigerated), do a three-cycle purge, then pressurize, keeping the regulator connected and putting everything in the fridge. At convenient moments with at least an hour interval, I’ll disconnect the gas and agitate the keg carefully. After 24hrs, I should have a cold, well-carbonated drink.

			Once I have it, I will first do a '''dry test''' to ensure I've put everything together well. I’ll put the keg in the fridge for an hour before starting this test. Then, I’ll connect the regulator, which will pressurize to ~1.6bar. I’ll leave it in for 20 minutes, then disconnect it, wait a few seconds and reconnect to hear what a reconnect should sound like without pressure loss. Then, I’ll leave it disconnected in the fridge for 24hrs, then reconnect the regulator and listen for any gas flow when I do. It should sound the same as before, indicating no pressure loss.
